Part 75 ECMPS Re-Engineering Update

On February 6, 2024, the EPA’s Clean Air Markets Division (CAMD) hosted a webinar to discuss modifications to the existing ECMPS 1.0 Client Tool to accommodate the Good Neighbor Rule and MATS Rule electronic reporting requirements that became effective January 1, 2024.  The deadline for implementing ECMPS 2.0 continues to be postponed indefinitely.  Indications are pointing to either a 2024 Q3 or 2025 Q1 implementation schedule, with 2025 the likely scenario.

The ECMPS 1.0 Client Tool MATS PDF Submit module will be modified to allow the submittal of XML, JSON, and PDF files and will be renamed accordingly.

CAMD stated that the release date for the stand-alone ECMPS Client Tool would follow the usual deployment schedule and take place around “mid-March.”  There were no personnel from EPA’s Office of Air Quality Planning and Standards (OAQPS) to clarify how certain reports would be formatted (XML vs. JSON vs. PDF).

The ECMPS 2.0 schema for the quarterly compliance report has not been finalized and the first report was anticipated to be in JSON format.  CAMD suggested that affected sources contact the delegated authority to obtain guidance on whether a PDF copy of the report could continue to be submitted in lieu of an XML or JSON.  The same confusion applies to the requirements to submit hourly PM CEMS data, hourly PM CPMS data, and 30/90-day rolling averages.  A recording of the webinar will be posted at but has not been loaded up yet.

All VIM Technologies customers running CEMLink6 who are subject to either the Good Neighbor Rule or the MATS Rule will require a CEMLink6 update before Q1 2024 reporting in April.  We are in the final phase of QC and will be prepared to release CEMLink6 Ver. 6.2.550 in late March.  This release will allow users to generate MATS quarterly compliance reports and PM CEMS quarterly emission reports in JSON format.

VIM recommends that MATS-affected sources contact their stack test contractors to ensure that they will provide the applicable required MATS stack test data elements specified in Sections 17 through 30 of Appendix E to the MATS Rule in XML format.  VIM is not planning to include a CEMLink6 module to generate XML files for MATS compliance tests for elements required in this section of the rule.

VIM Technologies will continue to stay on top of these changes and will provide an update when we know more.  In the meantime, please don’t hesitate to reach out to our COMPAS group ( if you have any questions.


ECMPS 2.0 Start Date Postponed

UPDATE: ECMPS 2.0 Start Date Postponed

On November 15, 2023, the EPA’s Clean Air Markets Division (CAMD) hosted a webinar to discuss transitioning from ECMPS 1.0 (i.e., the ECMPS Client Tool) to the new web-based ECMPS 2.0 reporting platform. During the webinar, CAMD announced that ECMPS 2.0 would not be used to report quarterly QA and emissions files as initially scheduled for Q1 2024. Additionally, CAMD did not specify a new start date for ECMPS 2.0. The agency does not want to postpone the ECMPS 2.0 implementation date more than once, so they intend to conduct a thorough assessment of the status of the software platform before setting a new realistic start date. CAMD indicated that they hope to complete this assessment before the end of 2023. The webinar was recorded, and a copy will be posted to the ECMPS Re-engineering Effort website at

Discover the New LME EDR Tool for ECMPS 2.0 by VIM Technologies

Beginning in the first quarter of 2024, Part 75 sources will be required to report their Electronic Data Reports (EDRs) using the new web-based ECMPS 2.0 platform. This change means that the original ECMPS standalone client tool will no longer be an option for reporting EDRs. This can create some challenges for organizations that need to prepare for this change.

VIM Technologies, a leading provider of innovative solutions for the energy industry, has developed a solution to address this challenge. VIM’s LME EDR Tool for ECMPS 2.0 is an advanced web-based utility tool that provides an efficient and cost-effective solution for creating Part 75 Low Mass Emitter (LME) XML & JSON formatted Electronic Data Reports (EDR).

The upcoming webinar, “LME EDR Tool for ECMPS 2.0,” hosted by VIM on May 24th from 1:00 PM to 1:45 PM ET, will provide an opportunity to learn more about this innovative tool. During the webinar, attendees will see a demonstration of the tool’s features and capabilities and have the chance to ask questions.  REGISTER HERE

The LME EDR Tool for ECMPS 2.0 is designed to help LME sources create and format their EDRs with ease and efficiency while ensuring the accuracy and completeness of their data. The tool is user-friendly and intuitive, allowing LME sources to quickly and easily create EDRs without requiring technical expertise. This feature ensures that users can adapt to the new system quickly.

Platform users can also manually enter operating and long-term fuel flow data or import a CSV file, one that’s been used for years in the current ECMPS client tool. If the existing CSV file import format isn’t suitable for you, or if it takes hours or labor, and resources to convert it, VIM can develop a custom import utility that matches your exact file format needs, thus reducing the need to convert and risk transcription errors.

In addition to being easy to use, the LME EDR Tool for ECMPS 2.0 is also highly secure and dependable. VIM has taken measures to ensure that the tool is safe and that data remains confidential. Users can trust that their data is protected and that they will be in compliance with regulations.

LME EDR Tool for ECMPS 2.0 is web-based, which means that LME sources can access it from anywhere with an internet connection. This feature allows users to work on their EDRs at any time that is convenient for them without needing to be in the same physical location.

Overall, the LME EDR Tool for ECMPS 2.0 is an essential solution for LME sources who want to improve their EDR reporting processes and ensure that their data is accurate, complete, and compliant with regulations. The upcoming webinar provides an excellent opportunity to learn more about this innovative tool and discover how it can benefit your organization.

EPA Publishes Proposed MATS Rule Revisions in Federal Register

On April 24, 2023, EPA published proposed revisions to the MATS Rule (Subpart UUUUU, 40 CFR Part 63) in the Federal Register. Comments on the proposed rule are due on or before June 23, 2023. EPA will hold a virtual public hearing on May 9, 2023. A copy of the proposed rule is available HERE.

As an overview, EPA is proposing to (1) eliminate the surrogate non-Hg metals HAP standard for filterable PM compliance for existing coal-fired EGUs; (2) require PM CEMS to demonstrate compliance with the applicable filterable PM limit (thereby eliminating the quarterly stack testing option); (3) set a new Hg emission limit for EGUs combusting lignite; and (4) remove “Startup Definition 2.”

The EPA Administrator signed the proposed MATS Rule on April 3, 2023. You can find a link to our previous website news post HERE, which features a redline/strikeout version of the proposed rule and a summary of the proposed revisions.

We welcome any questions or concerns you may have regarding the impact of these rule changes, and we would be more than happy to connect you with a regulatory specialist to discuss further. Please don’t hesitate to reach out to our COMPAS group at if you require any assistance. Additionally, if you need help updating your DAHS (Data Acquisition and Handling System) to ensure compliance with the changes, our support group at is always available and ready to help.
